Abstract
Description
Technical Field
[0001] This application relates to the field of titanium dioxide detection technology, and in particular to a titanium dioxide sample sampling and detection device. Background Technology
[0002] In the field of inorganic chemical pigments, titanium dioxide, with its excellent whiteness, hiding power, and tinting strength, has become an indispensable key raw material for many industries such as coatings, plastics, papermaking, printing inks, chemical fibers, rubber, and cosmetics. The quality of titanium dioxide plays a decisive role in the performance, quality, and stability of finished products manufactured by downstream industries. Therefore, throughout the entire process of titanium dioxide production, storage, and transportation, to ensure that product quality consistently meets standard requirements, regular sampling and testing of finished products are crucial. Precise control of key indicators such as particle size distribution, purity, and impurity content is a critical link in ensuring stable product quality and meeting the needs of downstream industries.
[0003] To meet the aforementioned sampling and testing requirements, various types of titanium dioxide sampling and testing devices are currently available on the market. Among these, the most common sampling method is the surface single-point sampling device. These devices typically use a simple sampling probe to obtain samples from a specific location on the surface of the material pile. Some devices design the sampling and testing processes as independent systems, first using the sampling equipment to obtain the sample, and then transferring the sample to a specialized testing instrument for analysis of various indicators. Additionally, some sampling devices prioritize sampling functionality in their structural design, but lack sufficient consideration for the device's own cleanliness.
[0004] Single-point sampling of the surface layer, because it can only obtain samples from the surface of the material, cannot cover the upper, middle, and lower layers of the material. This results in the sample not being able to fully represent the overall quality of the material, leading to a large sampling deviation and affecting the accurate judgment of product quality. The independent design of sampling and testing makes the sample highly susceptible to contamination by the external environment during transfer. Moreover, the entire testing process is cumbersome, requiring multiple operations and waiting times, resulting in long testing times and reduced testing efficiency. The difficulty in cleaning the sampling device makes residual powder prone to cross-contamination of new samples during subsequent sampling, seriously affecting the accuracy and reliability of the test results. Some complex sampling devices are cumbersome and inconvenient to operate, and cannot flexibly adapt to the sampling needs of titanium dioxide under different storage environments, limiting their versatility and effectiveness in practical applications.

Detailed Implementation
[0020] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.
[0021] For example, titanium dioxide, as an important white pigment, requires multi-point and multi-level sampling of the finished product for quality testing to ensure sample representativeness. Currently, titanium dioxide sampling and testing devices have the following drawbacks: 1. Insufficient sample representativeness: Single-point sampling is easily affected by localized inhomogeneities and cannot reflect the true state of the entire batch of materials; 2. Low operational efficiency: Manual multi-point sampling is time-consuming and prone to introducing human error; 3. Low testing integration: After sampling, samples need to be transferred to independent testing equipment, increasing intermediate steps and affecting timeliness; High risk of contamination: Residual materials in the sampling pipeline can easily lead to cross-contamination, affecting testing accuracy.
[0022] To address the technical problem that most of the aforementioned titanium dioxide sampling and testing devices use single-point sampling on the surface, which is insufficient to cover the upper, middle, and lower layers of the titanium dioxide material, resulting in significant sampling deviations and an inability to accurately reflect the overall quality of the titanium dioxide material, this application provides a titanium dioxide sample sampling and testing device. The titanium dioxide sample sampling and testing device is described below: like Figure 1 The diagram shown is a schematic diagram of the titanium dioxide sample sampling and testing device in this application.
[0023] This application provides a titanium dioxide sample sampling and testing device, comprising: The sampling and testing device body 1 has an internal cavity for accommodating titanium dioxide samples. One side of the sampling and testing device body 1 has an inlet 11 and an outlet 12, both connected to the internal cavity. The other side of the sampling and testing device body 1 has at least one detection port 13, one end of which is connected to the internal cavity, and the other end to a detection channel 2.
[0024] A driving device 3 is disposed in the receiving cavity and is used to drive the titanium dioxide sample to the discharge port 12 and the detection port 13.
[0025] The detection device 4 is disposed in the detection channel 2 and is used to detect the index parameters of the titanium dioxide sample. The index parameters include: titanium dioxide particle size distribution, purity and heavy metal content.
[0026] Specifically, by vertically inserting the titanium dioxide sample sampling and testing device into the titanium dioxide sample and activating the driving device 3, the titanium dioxide sample enters the receiving cavity through the feed port 11; driven by the driving device 3, it enters the testing channel 2 through the testing port 13, and the testing device 4 determines the index parameters of the titanium dioxide sample.
[0027] This application provides a titanium dioxide sample sampling and testing device. By vertically inserting the titanium dioxide sample sampling and testing device into the titanium dioxide material, multiple sampling points can be achieved by varying the insertion depth. This covers the upper, middle, and lower layers of the titanium dioxide material, thereby reducing sampling deviation. Furthermore, through the integrated design of the testing device 4 and the main body 1 of the sampling and testing device, the titanium dioxide sample material directly enters the detection channel 2 built into the main body 1 through the detection port 13 after sampling. The testing device 4 detects parameters such as particle size distribution, titanium dioxide purity, and heavy metal content of the titanium dioxide sample.
[0028] In this embodiment, the device further includes: A tip guide cavity 5 is disposed on the side of the sampling and detection device body 1 near the feed inlet 11; the tip guide cavity 5 is connected to the receiving cavity inside the sampling and detection device body 1; the cross-sectional area of the tip guide cavity 5 gradually decreases towards the side away from the sampling and detection device body 1.
[0029] For example, the tip guide cavity 5 serves as a sampling guide cavity, and the tip design reduces the contact area with the titanium dioxide sample. The tip, as the front end of the tip guide cavity 5, initially contacts the titanium dioxide sample. Its narrow opening design significantly reduces the initial contact area, facilitating the smooth insertion of the titanium dioxide sample sampling and detection device into the sample and avoiding disturbance to the overall sample structure, making it particularly suitable for powdery materials. Precise control of the sampling start position is achieved through tip positioning, ensuring that each sampling begins at the same depth and position, improving the consistency of multiple batch tests, and is suitable for quality control processes requiring high repeatability. Isolating the "unstable titanium dioxide sample at the beginning" prevents interference with detection. Upon initial contact, the titanium dioxide sample has not yet stably flowed into the detection path; this portion may contain air, residues, or unevenly composed "initial flow," resulting in unreliable quality. The tip guide cavity 5 can temporarily accommodate this portion of the titanium dioxide sample, preventing it from directly entering the detection area, acting as a "waste sample buffer" to ensure that the sample entering the detection channel 2 is a stable and representative mid-stage titanium dioxide sample. It reduces cross-contamination and residual effects. The cavity structure facilitates cleaning or purging, leaving little residue. Especially when continuously testing different batches of titanium dioxide samples, it can effectively reduce the mutual influence between different batches of titanium dioxide samples.
[0030] In this embodiment, the driving device 3 includes: A drive motor 31 is disposed on the side of the sampling and testing device body 1 away from the feed inlet 11; the power end of the drive motor 31 is connected to one end of the spiral conveyor blade 32; the spiral conveyor blade 32 is disposed in the receiving cavity inside the sampling and testing device body 1; the other end of the spiral conveyor blade 32 extends toward the tip guide cavity 5; the drive motor 31 is used to drive the spiral conveyor blade 32 to rotate, so as to carry the titanium dioxide sample to the discharge port 12 and the detection port 13.
[0031] In this embodiment, the device further includes: The material level detector 6 is disposed inside the receiving cavity inside the main body 1 of the sampling and detection device; the material level detector 6 is disposed on the side close to the drive motor 31; the material level detector 6 is used to detect the material level height of the titanium dioxide sample in the receiving cavity.
[0032] A controller is connected to the level detector 6 and the drive motor 31; the controller is configured to: The material level height of the titanium dioxide sample is obtained; if the material level height is less than the preset material level height, the drive motor 31 is controlled to operate at a first power; if the material level height is greater than or equal to the preset material level height, the drive motor 31 is controlled to operate at a second power.
[0033] Wherein, when the drive motor 31 operates at a first power, the rotational speed of the spiral conveying blade 32 is less than the rotational speed of the spiral conveying blade 32 when the drive motor 31 operates at a second power.
[0034] Understandably, when the titanium dioxide sample sampling and testing device is first inserted into the titanium dioxide sample, the amount of titanium dioxide sample in the receiving cavity inside the main body 1 of the sampling and testing device is small, i.e., the material level is low. Therefore, it is sufficient to control the drive motor 31 to operate at the first power. When the amount of titanium dioxide sample in the receiving cavity inside the main body 1 of the sampling and testing device is large, i.e., the material level is high, it is necessary to quickly transfer the titanium dioxide sample in the receiving cavity to the discharge port 12 and the detection port 13. Therefore, the drive motor 31 is controlled to operate at the second power, increasing the rotation speed of the spiral conveyor blade 32, so as to quickly transfer the titanium dioxide sample in the receiving cavity to the discharge port 12 and the detection port 13 to complete the titanium dioxide sample sampling and testing work.
[0035] like Figure 2 The diagram shown is a schematic diagram of the detection device 4 in this application.
[0036] In this embodiment, the detection device 4 includes: The laser particle size analyzer 41 is used to emit a laser to the titanium dioxide sample and determine the particle size distribution data of the titanium dioxide sample according to the principle of laser scattering.
[0037] Specifically, the titanium dioxide sample sampling and testing device transports the titanium dioxide sample to the built-in detection channel 2 via the spiral conveyor blade 32. The titanium dioxide sample then enters the detection area of the laser particle size analyzer 41. This instrument utilizes the principle of laser scattering, measuring the scattering angle and intensity distribution of the laser light by titanium dioxide particles, and combining this with algorithmic analysis to obtain the sample's particle size distribution data (such as key parameters like D10, D50, and D90), achieving rapid, non-contact particle size detection. The detection method of the laser particle size analyzer 41 will not be detailed here.
[0038] In this embodiment, the detection device 4 further includes: X-ray fluorescence spectrometer 42 is used to emit X-rays to the titanium dioxide sample and determine the purity and heavy metal content of the titanium dioxide sample based on the differences in fluorescence energy and intensity in the titanium dioxide sample.
[0039] Specifically, after particle size analysis, the titanium dioxide sample continues to flow to the detection area of the X-ray fluorescence spectrometer 42. The X-ray fluorescence spectrometer 42 excites atoms in the titanium dioxide sample to produce characteristic X-ray fluorescence. Based on the differences in fluorescence energy and intensity, it qualitatively and quantitatively analyzes the purity of titanium in the titanium dioxide, while simultaneously detecting the content of heavy metal impurities such as lead, mercury, and cadmium. The detection method of the X-ray fluorescence spectrometer 42 is not detailed here.
[0040] In this embodiment, the sampling and testing device body 1 is also provided with an air inlet 14 on the side near the feed inlet 11. The air inlet 14 is used to connect to a blower. The blower is used to release high-pressure gas into the receiving cavity inside the sampling and testing device body 1 through the air inlet 14, so that the titanium dioxide sample attached to the inner wall of the receiving cavity is detached.
[0041] Specifically, the high-pressure air source connected to the air inlet 14 can be equipped with a separate motor and blower or be independently supplied, eliminating the need for a motor and blower. It features a high-pressure air valve, a separate air path, and a control switch, utilizing the gas's own pressure to form a high-speed jet, resulting in a simpler structure and lower maintenance costs. Pulse-type backflushing can be configured to improve cleaning efficiency. When the control system is triggered, the high-pressure air valve (usually a solenoid valve) opens at high speed, releasing short-term high-pressure gas to form a shock wave that spreads along the chamber wall, effectively stripping away attached dust and ensuring that residual samples are thoroughly removed. The high-pressure backflushing cleaning has a dual-function design: cleaning and flow assistance. Normal cleaning mode: activated after batch testing to remove residues in the chamber and prevent cross-contamination of titanium dioxide samples. Blockage clearing mode: when titanium dioxide samples have poor flowability or the channel is blocked, the air valve can be temporarily opened, using airflow to push the titanium dioxide sample into the testing channel 2, ensuring process continuity.
[0042] In this embodiment, the high-pressure gas is nitrogen. Using nitrogen purging offers both protective and safety advantages; it not only prevents oxidation reactions from interfering with the detection results of titanium dioxide samples, but also reduces the risk of explosion in flammable dust environments.
[0043] In this embodiment, the detection device 4 is connected to the report generation device, which receives the index parameter data of the titanium dioxide sample and generates an index parameter report; the index parameter report displays the index parameters of the titanium dioxide sample. The report generation device can be a computer, which remotely receives the index parameter data of the titanium dioxide sample and generates an index parameter report using a set template, allowing users to obtain the detected titanium dioxide sample index parameters promptly and conveniently.
[0044] In this embodiment, the inner walls of the detection device body 1, inlet 11, outlet 12, detection port 13, air inlet 14, detection channel 2, and tip guide cavity 5 are made of inert material.
[0045] Specifically, all contact parts with the titanium dioxide sample are made of inert materials such as polytetrafluoroethylene (PTFE). These include the main body 1 of the detection device, the inlet 11, the outlet 12, the detection port 13, the air inlet 14, the detection channel 2, and the inner wall of the tip guide cavity 5. This ensures that impurities in the titanium dioxide sample do not react with the tube wall. PTFE has excellent non-stick and anti-fouling properties, extremely low surface tension, and is not prone to scaling or adhesion of media. It is particularly suitable for industries such as food processing and pharmaceuticals, facilitating cleaning and preventing cross-contamination, thus avoiding interference from raw material residues in different batches. PTFE also has an extremely low coefficient of friction and self-lubricating properties, which significantly reduces fluid transport resistance, reduces energy consumption, and improves the transmission efficiency of the titanium dioxide sample within the receiving cavity of the main body 1 of the sampling and detection device.
[0046] The above detailed embodiments further illustrate the purpose, technical solution, and beneficial effects of the embodiments of this application. It should be understood that the above are merely specific embodiments of the embodiments of this application and are not intended to limit the protection scope of the embodiments of this application.
